Objective To investigate the clinical efficacy of Xuanfei Tongluo Pingchuan Decoction in treating patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and to explore its regulatory mechanism on immune function and inflammatory response.Methods A retrospective study was conducted in 122 patients with AECOPD of phlegm-stasis obstructing lung type,and the patients were divided into an observation group and a control group according to the therapy,with 61 patients in each group.The control group was treated with conventional western medicine,and the observation group was treated with Xuanfei Tongluo Pingchuan Decoction on the basis of treatment for the control group.The treatment lasted for 14 days.Before and after treatment,the patients of the two groups were observed in the changes of pulmonary function indicators,6-minute walking distance(6MWD),COPD Assessment Test(CAT)scores,immune function indicators,and serum inflammatory factors.After treatment,the clinical efficacy and the overall occurrence rate of the adverse reactions were compared between the two groups.Results(1)After 14 days of treatment,the total effective rate of the observation group was 95.08%(58/61),and that of the control group was 77.05%(47/61).The intergroup comparison showed that the therapeutic effect of the observation group was significantly superior to that of the control group(P＜0.01).(2)After treatment,pulmonary function indexes such as the forced expiratory volume in one second(FEV1),forced vital capacity(FVC),and peak expiratory flow(PEF)of the two groups were significantly improved compared with those before treatment(P＜0.05),and the effect on improving all pulmonary function indexes in the observation group was significantly superior to that in the control group(P＜0.01).(3)After treatment,the 6MWD of the two groups were significantly higher(P＜0.05)and the CAT scores were significantly lower than those before treatment(P＜0.05),and the observation group was significantly superior to the control group in terms of improving the 6MWD and decreasing CAT scores(P＜0.01).(4)After treatment,the levels of immune function indicators of T lymphocyte subsets CD4+ and CD4+/CD8+ in the two groups were significantly higher than those before treatment(P＜0.05),and CD8+ level was significantly lower than that before treatment(P＜0.05),and the observation group had stronger effect on increasing T lymphocyte subsets CD4+ and CD4+/CD8+ levels and on decreasing CD8+ level than the control group(P＜0.01).(5)After treatment,the serum levels of inflammatory factors C-reactive protein(CRP)and tumor necrosis factor alpha(TNF-α)in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the effect on lowering the levels of serum CRP and TNF-α in the observation group was significantly superior to that in the control group(P＜0.01).(6)During the trial,the total incidence of adverse reactions in the observation group was 3.28%(2/61)and that in the control group was 6.56%(4/61),and the intergroup comparison showed that the difference was not statistically significant between the two groups(P＞0.05).Conclusion Xuanfei Tongluo Pingchuan Decoction can effectively alleviate the symptoms of cough and expectoration in AECOPD patients,improve the lung function and immune function,and reduce the inflammatory response.During the treatment,no obvious adverse reactions occur and the therapy is safe and effective.

Objective To explore the impact of high intensity focused ultrasound(HIFU)treatment on ovarian reserve capacity in adenomyosis.Methods Clinical data of 106 adenomyosis patients who underwent HIFU treatment from May 2019 to December 2020 at some hospital were analyzed retrospectively.All the patients were treated with HIFU,and color Doppler ultrasonography was performed before and after 6 months of treatment,respectively.The resistance index,pulsatility index,vascularization index,blood flow index,vascularization blood flow index and sinus follicle number were obtained,and serum anti-Mullerian hormone(AMH),follicle-stimulating hormone(FSH)and luteinizing hormone(luteinizing hormone)were measured.The correlation between serum AMH levels and FSH and LH levels was analyzed.SPSS 21.0 statistical software was used for data analysis.Results After 6 months of treatment serum FSH,LH,value of FSH/LH,resistance index and pulsatility index significantly decreased while vascularization index,blood flow index,vascularization blood flow index,number of sinus follicles,and serum AMH level obviously increased when compared with those before treatment,with the differences being statistically significant(P＜0.05).Serum AMH levels were negatively correlated with FSH and LH levels(r=-0.448,-0.527,P＜0.05)after 6 months of treatment.Conclusion HIFU treatment reduces sex hormone levels,elevates serum AMH levels and sinus follicle number,and may improve ovarian reserve capacity in patients with adenomyosis.[Chinese Medical Equipment Journal,2024,45(1):67-70]

Objective:To explore the clinical application of preimplantation genetic testing for monogenic disorders (PGT-M) in an unique case with Spinal muscular atrophy (SMA) type 2+ 0.Methods:A special SMA family presented at the Third Affiliated Hospital of Guangzhou Medical University on October 19, 2020 was selected as the study subject. Multiple ligation-dependent probe amplification (MLPA) and molecular tagging linkage analysis were carried out to identify the SMN1 genotype of the couple and their fetus. Subsequently, next-generation sequencing (NGS), molecular tagging linkage analysis, and chromosomal microarray analysis were employed to determine the haplotypes and validate the result of PGT-M on the 11 embryos derived for the couple. Results:The female partner was identified as a carrier of the rare SMN1[2+ 0] variant, and prenatal diagnosis confirmed the fetus to be affected by SMA. Ultimately, PGT-M has successfully selected four embryos free from the pathogenic SMN1 variants and X chromosome deletion. Conclusion:PGT-M can effectively prevent the transmission of rare genetic variants such as the SMA 2+ 0 subtype in the families. Above finding has provided guidance for genetic counseling and family planning for the couple.

[ Abstract ] Objective To explore the effect of 3D print-based navigation module assisted placement of thoracolumbar pedicle screws. Methods From January 2019 to May 2021, we received 70 thoracic and lumbar fracture patients, divided into 3D technical group and conventional method group according to the surgical method, with 35 patients in each group. In the 3D technology group, pedicle screws were placed under the sight of the navigation module, while in the conventional group, pedicle screws were placed under the conventional C-arm fluoroscopy. The amount of intraoperative bleeding and time of C arm were counted in each patient. According to the different number of pedicle screw implantation in each patient, the average amount of blood loss, time and C-arm fluoroscopy times of each screw implantation were compared between the two groups. Ideal screw angles were designed for patients in both groups before surgery. Compared with the preoperative design, the difference between preoperative and postoperative screw angle and head angle was calculated and set as the deviation value. Two sets of data were compared. Visual analogue score(VAS), Japanese Orthopaedic Association (JOA) score, Oswestry disability index(ODI), vertebral height recovery ratio and Cobb’ s angle were compared between the two groups. Results The amount of blood loss, required time and exposure times of C-arm in 3D screw implantation group were significantly lower than those in conventional screw implantation group(P<0. 05); After operation, the deviation of ininclination and head angle in the conventional method group was higher than that in the 3D technique group, and the difference was significant(P<0. 05); The VAS, JOA score, ODI, vertebral height recovery ratio and Cobb’s angle were significantly improved compared with the preoperative groups(P<0. 05); Three months after surgery, the VAS, JOA score, and ODI were not significantly different between the two groups (P>0. 05); In terms of Cobb’s angle and vertebral height recovery ratio, the 3D technique group was better than the conventional method group (P<0. 05). Conclusion The 3D printed navigation module can assist the precise placement of thoracolumbar pedicle screws, shorten the operation time, reduce intraoperative bleeding and c-arm exposure times, facilitate the recovery of the injured vertebral height, improve the efficacy.
